If you’re going through withdrawal right now, the most important thing is to stay safe, stay hydrated, and get support. Withdrawal symptoms vary widely depending on the substance, how long you’ve used it, and your overall health, but the core steps are the same: manage your physical symptoms, ride out cravings, and know when the situation requires medical help. Most withdrawal episodes follow a predictable timeline, and knowing what to expect makes the process significantly easier to get through.
Know When It’s a Medical Emergency
Not all withdrawal is equally dangerous. Withdrawal from alcohol and sedatives (like benzodiazepines) can be life-threatening, and stopping cold turkey without medical supervision is risky if you’ve been using heavily. The most serious complication of alcohol withdrawal, called delirium tremens, typically appears 48 to 96 hours after the last drink, though it can show up as late as 7 to 10 days afterward. Symptoms include confusion, hallucinations, seizures, a dangerously fast or irregular heartbeat, and severe spikes in blood pressure. This is a medical emergency that requires immediate care.
If you or someone near you is experiencing seizures, chest pain, severe confusion, hallucinations, or thoughts of suicide during withdrawal from any substance, call 911. These are signs the body can’t safely manage the process on its own.
What Withdrawal Feels Like by Substance
The symptoms and timeline depend on what you’re withdrawing from. Here’s what to expect for the most common substances:
Alcohol
Mild symptoms like anxiety, shaking hands, sweating, and nausea often start within 6 to 12 hours after the last drink. These can escalate over the next two to three days. Anyone with a history of heavy, daily drinking should talk to a medical provider before stopping, because the risk of seizures and delirium tremens is real and unpredictable.
Opioids
Opioid withdrawal is intensely uncomfortable but rarely life-threatening on its own. Expect muscle aches, nausea, diarrhea, sweating, anxiety, and insomnia. Symptoms usually start within 8 to 24 hours of the last dose for short-acting opioids and can last a week or more. The worst of it typically peaks around days two and three.
Nicotine
Nicotine withdrawal peaks on the second or third day after quitting. You’ll likely feel irritable, anxious, and have trouble concentrating, along with strong cravings. Physical symptoms generally fade over three to four weeks, though cravings can linger longer.
Antidepressants
Stopping SSRIs or similar medications abruptly can cause what’s sometimes called discontinuation syndrome: dizziness, “brain zaps” (brief electric shock sensations), flu-like symptoms, irritability, and vivid dreams. This is why these medications should always be tapered gradually under a prescriber’s guidance rather than stopped all at once.
Immediate Steps to Take Right Now
Whether you’re withdrawing from nicotine, opioids, alcohol, or something else, these basics help stabilize your body and make the process more bearable.
Hydrate aggressively. Withdrawal often causes sweating, vomiting, or diarrhea, all of which drain your body of fluids and essential minerals. Drink water consistently, and use an electrolyte solution like Pedialyte or a sports drink to replace what you’re losing. Dehydration makes every symptom worse, from headaches to heart rate spikes.
Eat what you can. Your appetite will probably be low, but your body needs fuel. Small, bland meals are easier to keep down. Crackers, bananas, rice, toast, and broth are good starting points. A small amount of chocolate can also help with mood and energy when you’re feeling depleted.
Manage pain and nausea with what’s available. For muscle aches and body pain, over-the-counter options like ibuprofen or acetaminophen can take the edge off. For nausea, ginger tea or ginger chews are a simple, accessible option. If you’re able to see a doctor, they can prescribe stronger anti-nausea medication.
Control your environment. Keep the room at a comfortable temperature. Have extra blankets nearby for chills and a fan for hot flashes. Dim the lights if you’re sensitive to stimulation. Reducing sensory input helps your nervous system settle.
How to Handle Cravings
Cravings are the hardest part for most people, and they feel overwhelming in the moment. But a single craving typically peaks and fades within 15 to 30 minutes if you don’t act on it. The goal is to ride out that wave.
One effective technique is to delay and distract. When a craving hits, commit to waiting it out for a set amount of time, 10 or 15 minutes, and fill that window with something that occupies your hands or your mind. Go for a walk, take a shower, text someone, do a household task, write in a journal. The craving will lose intensity if you give it time without feeding it.
Another approach involves examining the thoughts that accompany the craving. Your brain will generate “permission-giving beliefs,” things like “just one won’t hurt” or “I can’t handle this without it.” Writing these thoughts down and then writing a realistic response next to each one helps break their power. For example, next to “just one won’t hurt,” you might write “one always leads to more, and I’ll be back at square one.” This isn’t about willpower. It’s about catching the distorted thinking that makes using feel logical when it isn’t.
It also helps to keep a written list of the reasons you’re going through this. The pros of staying sober versus the pros of using, laid out clearly, give you something concrete to look at when your thinking gets foggy. Withdrawal temporarily impairs your ability to think clearly, so having these things written down before the worst hits is valuable.
Who Should Seek Medical Detox
Some people can safely manage withdrawal at home, especially for nicotine or mild opioid dependence. Others need medical supervision. The general criteria for inpatient detox include situations where withdrawal is causing or could cause seizures, dangerously high blood pressure, psychosis, hallucinations, or active suicidal thoughts. If you also have a serious medical condition on top of withdrawal, that raises the risk further.
If you’re unsure whether your situation requires medical help, err on the side of caution. This is especially true for alcohol and benzodiazepine withdrawal, where complications can appear suddenly even in people who seem stable.
For opioid dependence specifically, medication-assisted treatment with options like buprenorphine or methadone can dramatically reduce withdrawal severity and improve long-term outcomes. These aren’t available over the counter, but a provider can prescribe them, sometimes on the same day you seek help.
Getting Help and Support
SAMHSA’s National Helpline is free, confidential, and available 24 hours a day, 365 days a year. Call 1-800-662-4357 to be connected with local treatment facilities, support groups, and community organizations in your area. The service is available in English and Spanish. You can also text your ZIP code to 435748 (HELP4U) to find services near you. The helpline doesn’t provide counseling directly, but trained specialists will connect you with the right resources in your state.
If you have someone you trust, tell them what you’re going through. Having another person check in on you, even by phone, adds a layer of safety and makes the isolation of withdrawal less intense. Support groups, both in-person and online, provide a space where people who have been through the same thing can offer practical advice and accountability.
What to Expect After the Worst Passes
Physical withdrawal symptoms are temporary, even though they don’t feel that way in the middle of them. For most substances, the acute phase lasts somewhere between a few days and two weeks. What often lingers longer is the psychological side: disrupted sleep, low mood, anxiety, and recurring cravings. This is normal and not a sign that something is wrong with you. Your brain is recalibrating after functioning with the substance for an extended period, and that process takes time.
Sleep disruption is one of the most persistent issues. It can take weeks for your sleep cycle to normalize. Keeping a consistent wake time, avoiding screens before bed, and getting physical activity during the day all help speed this along. Resist the temptation to use sleep aids or other substances to compensate, as this can create a new dependency cycle.
The period immediately after acute withdrawal is when relapse risk is highest. Having a plan in place, whether that’s ongoing therapy, a support group, medication-assisted treatment, or simply a daily structure that keeps you occupied, makes a measurable difference in long-term recovery.
